Makoto Kousaka stands out in the Genshiken club as a video game expert, especially skilled in competitive fighting games and pornographic titles. His appearance breaks otaku stereotypes: fashionable blonde hair (likely dyed), a hairless body, and an hourglass figure enabling convincing female cosplay. This attractiveness aids club marketing and draws admirers like Keiko Sasahara. He was bald as a child, mocked by his childhood friend and eventual girlfriend, Saki Kasukabe.

Personally, Kousaka maintains a consistently cheerful, friendly demeanor, nearly always smiling. He openly discusses his otaku interests with blunt honesty. Despite dating Saki, he frequently prioritizes hobbies, even adjusting positions during intimacy to watch anime. His intense gaming focus allows him to dominate tournaments like Comifest during extended sessions.

Born February 2, 1984 (Aquarius, blood type B), Kousaka favors the manga *The Mysterious Adventures of DaDa* and games like *Full Armor* and *Street Master 2*, using the pen name Toshizo. He remained oblivious to Saki's romantic feelings until another club member intervened. Their relationship, strained by his hobby focus, gradually increases Saki's tolerance for otaku culture.

After university, Kousaka becomes a programmer for a pornographic game developer. This career shift reduces his previous balance between fashion and hobbies. He consistently participates in club activities, including cosplaying to boost merchandise sales. His non-stereotypical identity—blending conventional attractiveness and sociability with otaku passions—challenges social perceptions.

His arc concludes with ongoing stability in his relationship with Saki and professional fulfillment, illustrating how personal passions coexist with interpersonal commitments despite friction.
